About Me

I am a starting researcher at Inria Saclay in the CEDAR team and part-time assistant professor at École polytechnique. Previously, I was a postdoctoral researcher at Max Planck Institute for Informatics in the team of Gerhard Weikum. I received my Ph.D. from Télécom Paris University and my advisor was Mauro Sozio.

My research interests lie in the area of data mining, with a focus on graph mining and computational social science.

Originally I am from Romania and more exactly Rucăr, a village in the Carpathian Mountains.

I am currently a part time assistant professor at École polytechnique, teaching courses and/or lab session for INF473G and INF583.
In the past I supervised classes as a teaching assistant at Télécom Paris.


In my free time I enjoy reading and painting using watercolors.
My sister writes very nice stories and travel impressions (in Romanian).
